TYPEWRITERSEGURING DEVICE.

Application filed August.1, 1923. Serialv No. 655,138.

To all whom it may concern Be it known that we, Jnssn R. HENSLEY andCHARLES C. LAcY, citizens of the United States, residing at SanFrancisco, in the county of San Francisco and State of Calito produce adevice which may be attached.

to a table or other support for the purpose of remo-vably securingatypewriter frame thereto. It is obvious, :however, that this securingdevice might be used for other similar purposes.

Another object of this invention is to provide a device which isextremely simple, one which may be applied by the average person and onewhich will accommodate itself to various makes of typewriters and likemachines.

A still further object is to produce a device of this character which isextremely cheap to manufacture.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings forming apart of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a fragmentary detail view of a base of a typewriter showingour invention applied thereto, the same being partly in cross section,

Figure 2 is a perspective view of the clamp per se, and

Figure 3 is a cross section through the frame and support, the viewbeing taken on the line 33 of Figure 1.

In the manipulation of a typewriter and like machines where the keys arestruck, the machine has a tendency to move over the support upon whichit is resting and it is therefore essential that some means be providedfor preventing this movement and heretofore long screws have beenemployed extending through the support with the result that it has beena tedious process to move a machine as these screws had to be removed.We have therefore provided a simple device which will obviate thisdifficulty. I

In the accompanying drawings wherein for the purpose of illustration isshown a preferred embodiment of our invention, the numeral 5 designatesthebase of a typewriter or like machine equipped with the usual legs 6and 7, while the numeral 8 rep:

resents the topsurface of the table or like support to which our deviceis attached.

As. shown to advantage in Figure 2, the device embodies in itsconstruction a U- shaped base 9 having an upwardly extend.

ing U-shaped collar .11 formed integral with the inner margin of theU-shaped base .9... This upstanding collar .is provided with an inwardlyextending flange 12. which is. adapted to be; contacted by thehead 13 ofa partly threaded bolt 14, the threaded end of which is secured to a lug16 formed integral with the base 5, which lug 16, as well as the nut- 17are common to all makes of machines.

The U-shaped base 9 of our device is detachably secured to the supportor table top by suitable screws or the like 17'. It will be noted that aprotuberance 18 is formed upon the upper surface of the collar 11, whichprotuberance supports thereon the rear portion of a washer 19 encirclingthe bolt 14 and causes the washer to be angu-- larly disposed withrelation to the surface of the collar, as disclosed to advantage inFigure 1.

The numerals 20 and 21 designate extensions formed upon the collar,which extensions serve to retain the washer in position and co-operate'with the washer so as to accomplish a locking of the bolt in the device.It will be noted that the extensions are cut away as at 22 and 23respectively so that they conform to the contour of the outer peripheryof the washer and thus a positive locking action of the washer withrelation to the extensions is assured.

I The operation of our device is as follows y Two of the devices arefastened upon the support or table top at proper distances apart so asto underlie the two downwardly extending bolts 14. Each bolt ispositioned.

head 13 has reached the position shown in v Figure 1. The washers arethen dropped and will assume the full line position disclosed inFigure 1. When it is desired to remove the machine the finger of theoperator is placed upon the raised end A of thewasher and presseddownwardly, as disclosed in the dotted line position in Figure 1. Thisaction causes the respective washer to tilt over the protuberance 17,thus raising the front of the washer out of engagement with theextensions 19 and 21.

The frame as a whole may then be moved forwardly and the bolt head 13disengaged from the inwardly extending flange of our device.

It is to be understood that the form of our invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and. arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described our invention, we claim 1. In a typewritersecuring device, the combination with a typewriter frame and its pendantheaded bolt, of a U-shaped base member, an upwardly extending recessed Ushaped collar formed integral therewith and adapted to receivetherebeneath the head of the bolt and having formed on its upper surfacea spaced extension and a protuber ance, and a washer encircling the boltand adapted to rest upon the protuberance and contact the rear of theextensions, for the purpose specified.

2. A securing device comprising a U- shaped base, a collar formedintegral with said base and being provided on its upper surface withextensions and a protuberance remote from the extensions of said collar,a bolt adapted to have its head underlie the collar, and a washervertically movable on the bolt and adapted to contact theprotuberanceand extensions of the collar, for the purpose specified.

In testimony whereof we affix our signatures.
